Intermittent dry granular flow in a vertical pipe
Yann Bertho, Frederique Giorgiutti-Dauphine, Jean-Pierre Hulin
The intermittent compact flow of glass beads in a vertical glass pipe of small diameter is studied experimentally by combining particle fraction, pressure, and air and grain flow r…
Influence of humidity on granular packings with moving walls
Y. Bertho, Th. Brunet, F. Giorgiutti-Dauphine +1
A significant dependence on the relative humidity H for the apparent mass (Mapp) measured at the bottom of a granular packing inside a vertical tube in relative motion is demonstra…
Dynamical Janssen effect on granular packings with moving walls
Yann Bertho, Frederique Giorgiutti-Dauphine, Jean-Pierre Hulin
Apparent mass measurements at the bottom of granular packings inside a vertical tube in relative motion are reported. They demonstrate that Janssen's model is valid over a broad ra…
